Its primary job is to clear faults on distribution feeders and branch circuits in commercial and industrial switchboards, panelboards, and MCC buckets. That 630 A figure is the one you size busbars and upstream protection for; the 520 A floor at 70 °C tells you how much headroom you lose in a hot enclosure. Maximum power loss of 162 W means this breaker dumps heat into the panel — account for ventilation if the enclosure is sealed. Breaking capacity is 330 kA at 240 V, 242 kA at 415/440 V, 187 kA at 500 V, and 9 kA at 690 V. Physical footprint: 110 mm deep, 138 mm wide, 248 mm tall. Fits standard 600 mm-wide MCC buckets and panelboard gutters without clearance issues. The trip indicator provides a visual flag when the breaker has tripped on fault — no need to open the enclosure door to check status.
Integration Notes
Designed as a line-protection MCCB in the SENTRON family — mounts in standard panelboard or MCC bucket cutouts. The 3-pole form factor with no undervoltage release and no ground-fault monitoring means it is a straight thermal-magnetic or electronic-trip breaker for basic feeder protection.
